Abstract
A speed control device includes: a vehicle information output unit that outputs at least two, as vehicle information, of measurement information on forward/backward acceleration of a vehicle measured by an acceleration sensor, forward/backward actual acceleration of the vehicle obtained from an output rotation of an automatic transmission, and a traveling driving force based on a driving force output by a driving source and an air resistance acting on the vehicle; and a setting unit that selects a shift mode by comparing the vehicle information with a predetermined selection threshold and sets a shift point for controlling the automatic transmission provided in the vehicle based on the shift mode.
Claims3
A speed control device comprising:
- a vehicle information output unit that outputs at least two, as vehicle information, of measurement information on forward/backward acceleration of a vehicle measured by an acceleration sensor, forward/backward actual acceleration of the vehicle obtained from an output rotation of an automatic transmission, and a traveling driving force calculated by subtracting an air resistance acting on the vehicle from a driving force output by a driving source;
- and
- a setting unit that selects a shift mode by comparing the vehicle information with a predetermined selection threshold and sets a shift point for controlling the automatic transmission provided in the vehicle based on the shift mode,
- wherein the setting unit selects the shift mode by comparing the selection threshold according to a vehicle weight which is a weight of the vehicle with the vehicle information.
A speed control device, comprising:
- a vehicle information output unit that outputs an acceleration sensor value based on forward/backward acceleration of a vehicle measured by an acceleration sensor, and a traveling driving force calculated by subtracting an air resistance acting on the vehicle from a driving force of a driving source of the vehicle, and
- a setting unit that determines a relationship between a plurality of the acceleration sensor values and a plurality of the traveling driving forces, and corrects the acceleration sensor value by a difference between the relationship and a reference relationship.
